How to Fix CVE-2023-39525

To remediate this vulnerability, upgrade all affected Prestashop/prestashop dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

prestashop/prestashop fixed: 8.1.1 
Upgrade prestashop/prestashop to 8.1.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for prestashop/prestashop

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-39525, inspect your project dependencies for Prestashop/prestashop:

inspect dependencies for prestashop/prestashop

Analyze the terminal output to locate any version of Prestashop/prestashop in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.1.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Prestashop/prestashop, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In the back office, files can be compromised using path traversal by replaying the import file deletion query with a specified file path, using traversal path. ### Patches 8.1.1 ### Found by Aleksey Solovev (Positive Technologies) ### Workarounds none ### References none
